16 p, 2.4 MB Alteration of spodumene to cookeite and its pressure and temperature stability conditions in Li-bearing aplite-pegmatites from northern Portugal / Bobos, Iuliu (Universidade do Porto) ; Vieillard, Philippe (Université de Poitiers) ; Charoy, Bernard (Ecole Normale Supérieure de Géologie) ; Noronha, Fernando (Universidade do Porto)
The alteration of spodumene to cookeite has been identified in a Li-bearing aplite-pegmatite from northern Portugal. Optical microscopy and scanning and transmission electron microscopy (SEM/TEM) were used to characterize the alteration products in both cookeite + quartz and cookeite, + kaolinite ± mica assemblages. [...]

12 p, 1.2 MB Crystallochemical characterization of the palygorskite and sepiolite from the Allou Kagne deposit, Senegal / García-Romero, E. (Universidad Complutense de Madrid. Departamento de Cristalografía y Mineralogía) ; Suárez, M. (Universidad de Salamanca. Departamento de Geología) ; Santarén, J. (TOLSA) ; Álvarez Berenguer, Antonio (TOLSA)
The Allou Kagne (Senegal) deposit consists of different proportions of palygorskite and sepiolite, and these are associated with small quantities of quartz and X-ray amorphous silica as impurities. No pure palygorskite or sepiolite has been recognized by X-ray diffraction. [...]

20 p, 2.2 MB Mineralogy and geochemistry of the host-rock alterations associated with the Shea Creek unconformity-type uranium deposits (Athabasca Basin, Saskatchewan, Canada). Part 1. Spatial variation of illite properties / Laverret, Emmanuel (University of Poitiers) ; Patrier Mas, Patricia (University of Poitiers) ; Beaufort, Daniel (University of Poitiers) ; Kister, Philippe (Centre National de la Recherche Scientifique (França)) ; Quirt, David (Saskatchewan Research Council) ; Bruneton, Patrice (Business Unit Mines) ; Clauer, Norbert (Centre de Géochimie de la Surface)
Unconformity-related uranium deposits, which represent a significant high-grade uranium resource, are systematically surrounded by a host-rock alteration halo enriched in clay minerals. Illite is often the major clay mineral component of the halo and it displays a variable crystal structure. [...]

Department of Inorganic Chemistry I) ; Butterhof, Christian (University of Bayreuth. Department of Inorganic Chemistry I) ; Koch, Sebastian (University of Bayreuth. Department of Inorganic Chemistry I) ; Mariychuk, Ruslan (University of Bayreuth. Department of Inorganic Chemistry I) ; Breu, Josef (University of Bayreuth. Department of Inorganic Chemistry I)
Large transition-metal contents add desirable physical properties, such as redox reactivity, magnetism, and electric or ionic conductivity to micas and make them interesting for a variety of materials-science applications. [...]

13 p, 1.2 MB Al-saturated phlogopite : Charge considerations and crystal chemistry / Bujnowski, Thomas J. (University of Illinois at Chicago. Department of Earth and Environmental Sciences) ; Guggenheim, Stephen (University of Illinois at Chicago. Department of Earth and Environmental Sciences) ; Brigatti, Maria Franca (Università di Modena e Reggio Emilia. Dipartimento di Scienze della Terra)
Factors controlling the crystal structure of phlogopite have been widely investigated; but the role of electrostatic interactions, for example, has received much less attention than other factors. The purpose of the present study was to peform a single-crystal refinement of an Al-saturated phlogopite and to use that refinement to supplement crystal-chemical analyses. [...]

13 p, 1.8 MB Mineralogical evolution of a claystone after reaction with iron under thermal gradient / Jodin-Caumon, Marie-Camille (Université de Lorraine) ; Mosser-Ruck, Régine (Université de Lorraine) ; Randi, Aurélien (Université de Lorraine) ; Pierron, Olivier (Université de Lorraine) ; Cathelineau, Michel (Université de Lorraine) ; Michau, Nicolas (Agence nationale pour la gestion des déchets radioactifs)
The design of the repository for high-level nuclear waste (HLW) in France consists of a multiple-barrier system including steel canisters in a clay host rock. The system will undergo temperature variations in time and space, the heat source being the HLW within the canisters. [...]
